Especially, a hierarcical data structure is introduced to represent a set of relations which are inherently hierarchical. A retrieval procedure using data accesses along a two level hierarchy is obtained from an original formula on flat relations by applying equivalence transformation rules and data representation mappings.","doi":null,"url":"https://ijcai.org/proceedings/1981/193","pdf":"https://ijcai.org/proceedings/1981/0193.pdf","markdown":"https://ijcai.org/proceedings/1981/193.md","bibtex":"https://ijcai.org/proceedings/1981/bibtex/193","volume":{"slug":"1981","title":"Proceedings of the Seventh International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1981","url":"https://ijcai.org/proceedings/1981/","year":1981,"location":"Vancouver, British Columbia, Canada","dates":"24-28 August 1981","editors":"Roger C.
